The role of neoadjuvant chemotherapy in children with malignant solid tumors.

Pediatric surgeons play a critical role in diagnosing, staging, and treating malignant solid tumors in children. Over the years, the surgical management of the primary tumor site has evolved from an aggressive en-bloc resection at diagnosis to a more tailored surgical approach, often affecting definitive local control after the delivery of neoadjuvant therapy, as currently directed by many solid tumor protocols. In fact, inappropriate upfront resection can lead to unnecessary short- and long-term morbidity, an incomplete resection, and may be associated with a delay in the initiation of the systemic chemotherapy that is critical to the treatment of gross or occult metastatic disease. Therefore, it is important for the pediatric surgeon, as a member of the multidisciplinary team involved in the care of these children, to understand the indications for and implications of neoadjuvant therapy in the treatment of pediatric solid tumors. Here we review the current management of childhood solid tumors focusing on the role of neoadjuvant therapy.
